Hi,
When I configured MQ series to intergrate with DB2 using enable_MQFuntions in AIX box, I encountered below error :
/home/db2inst1/sqllib/cfg> enable_MQFunctions -n db1 -u db2inst1 -p db2inst1
*** Please wait: creating queue manager (DB2MQ_DEFAULT_MQM) ......
*** Please wait: starting the queue manager (DB2MQ_DEFAULT_MQM) ......
*** Error -- while connecting to DB2MQ_DEFAULT_MQM failed (reason code -- 2058)
crtmqm/strmqm has been issued
*** Problem -- while checking MQ
Please ensure that the user has permission to create/start start queue manager
Please ensure that the user has permission to create a queue
*** enable_MQFunctions Failed .....
Please ensure that MQSeries is installed properly
*** Please allow a few seconds to clean up the system ......
Any body know why? Fyi, I'm using db2inst1 to configure and my DB2 instance is belong to db2inst1 also.
Thanks
Regards,
fcho |

| Obvious question, but is your user ID in the "mqm" group? |

Strange - what happens when you do the crtmqm and strmqm manually - what errors do you get?
crtmqm DB2MQ_DEFAULT_MQM
strmqm DB2MQ_DEFAULT_MQM |

Any FDC files? Perhaps you could send the first 30 lines of an FDC file?
Another obvious question, have you changed your Kernel params AND REBOOTED? |

What is FDC files? Where is the file locate?
What Kernel params need to change? How to change it?
Sorry to say that I'm very new to AIX and MQ. Very thank you to you. |

Ah - AIX. Don't think there are any necessary kernel params there, I'll look.
FDC files are to be found in /var/mqm/errors - the name of the files are :
AMQ<process num>.0.FDC
look at the one (if there is one) generated around the time you did the "crtmqm".
More later... |

...got your FDC file, the problem relates to getting some shared memory. As far as I can see there are no relevant kernel parms on AIX, so it's not that, BUT it seems you need the command EXTSHM=ON (this sets an environment variable to tell MQ to use extended shared memory) before you use MQ. Could you try this and recreate?
EXTSHM=ON
crtmqm DB2MQ_DEFAULT_MQM
strmqm DB2MQ_DEFAULT_MQM
Don't forget, the CASE of commands (upper/lower) is important in Unix!
Anyway, I've attached a snippet, my AIX is a bit rusty, maybe somebody else would like to comment?

I must admit I'm a bit stuck as well, I'll throw in my $0.02 until somebody with more AIX than I have can help.... 
Ae there any other queue managers running on this system? Check with a ps -ef|grep zxma. Maybe a good idea to do a "ps -fu mqm" as well to see if anything is hanging around.
Post the file /var/mqm/mqs.ini - maybe a clue there.
IF THERE ARE NO OTHER QUEUE MANAGERS ON THE SYSTEM, clear out old shared memory stuff using:
#!/bin/sh
# zapmq - clear out IPCS stuff for ALL queue managers
#
temp=/tmp/zapmq.$$
ipcs|grep mqm|awk '{print "ipcrm -"$1" "$2}'>$temp
. $temp
rm $temp
WARNING: If you run this when a queue manager is running, YOU WILL CORRUPT IT.
Getting desperate here, but did the installation of MQ go okay? Has anybody used MQ successfully on this box?
And really desperate, have you rebooted? This fixes everything!

Hi,
My AIX got few Q mgr and all are running. I still don't know what happen but I'm able to solve this with execute other user .profile first before perform enable_MQFunctions. So I think the problem is on .profile but don't know what is the root cause.
Anywhere thanks a lot.

| I thought that you might be interested in knowing what your problem was in case you (or somebody else) sees it again. This is another variation of the segment 8 problem. MQSeries doesn't use extended shared memory. You have an EXTSHM=ON in the failing profile and don't have one in the one that works. If you'll move to WebSphere MQ 5.3, MQSeries will use the EXTSHM and you shouldn't see this problem. |

Hi bower5932,
I facing another problem when try to configure for MQ for second database as below :
enable_MQFunctions -n testDB -u testdb -p testdb
*** Please wait: creating queue manager (DB2MQ_DEFAULT_MQM) ......
*** Please wait: starting the queue manager (DB2MQ_DEFAULT_MQM) ......
(0) db2mq UDFs were found
-- Create MQ Functions ...
Validate MQ Functions ...
*** Error -- while validating DB2MQ functions
Please check that:
1. repository files and amt.dtd file are present in directory AMT_DATA_PATH
2. 'DB2.DEFAULT.SERVICE' is pointing to
queue_manager: DB2MQ_DEFAULT_MQM
queue: DB2MQ_DEFAULT_Q
3. 'DB2.DEFAULT.POLICY' is pointing to
connection name: connectionDB2MQ
4. amthost.xml contains 'connectionDB2MQ = DB2MQ_DEFAULT_MQM'
*** enable_MQFunction finished with error
*** Please allow a few seconds to clean up the system ......
I've check AMT_DATA_PATH, DB2.DEFAULT.SERVICE, DB2.DEFAULT.POLICY and amthost.xml, all are ok and I also try to use a sending program which point to the same amt.xml, this is no problem.
When I try to use db2 to send, problem also, refer to below :
db2 => values db2mq.mqsend('a test');
1
-
SQL0443N Routine "DB2MQ.MQSEND" (specific name "MQSND1") has returned an
error SQLSTATE with diagnostic text "rc=49:amSndOpen". SQLSTATE=38H01
I've tried to disable and enable agains MQ function but still the same, do you know why?
